Programmable sinusoidal oscillator circuit

摘要

A programmable sinusoidal oscillator circuit is a sinusoidal oscillator circuit that includes a current-feedback operational-amplifier (CFOA) operably connected to two operational transconductance amplifiers (OTAs), two capacitors and a resistor. The programmable sinusoidal oscillator circuit enjoys electronic orthogonal tuning of the frequency and the condition of oscillation by adjusting the biasing currents (voltages) of the OTAs, as well as providing a low output impedance.
